selenium: [🐛 Bug]: TimeoutException when trying to intercept traffic with selenium grid

What happened?

I’m trying to capture and modify a network call. I’ve prepared a sample project to reproduce the issue. https://github.com/baflQA/selenium-debug First, I start the selenium grid using docker-selenium images (https://github.com/baflQA/selenium-debug/blob/main/runGridStandalone.sh) Then, I start a new browser. The driver is augmented, the devTool connection is initiated. I navigate to a webpage, and capture some response. I get this response data, and store it in a variable. Then, I modify captured response. Finally, I create a new NetworkInterceptor instance, in order to capture and replace the original response for a given request with the modified one. I try to refresh the page, but once the network interceptor is registered, all the network traffic will be blocked. As a result, there will be an error thrown: System info: os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '13.5.1', java.version: '11.0.20' Driver info: driver.version: unknown at org.openqa.selenium.devtools.Connection$Listener.lambda$onText$0(Connection.java:227) at java.base/java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1128) at java.base/java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:628) at java.base/java.lang.Thread.run(Thread.java:829) Caused by: org.openqa.selenium.TimeoutException: java.util.concurrent.TimeoutException Build info: version: '4.12.1', revision: '8e34639b11' System info: os.name: 'Mac OS X', os.arch: 'x86_64', os.version: '13.5.1', java.version: '11.0.20' Driver info: driver.version: unknown at org.openqa.selenium.devtools.Connection.sendAndWait(Connection.java:183) at org.openqa.selenium.devtools.DevTools.send(DevTools.java:89) at org.openqa.selenium.devtools.idealized.Network.lambda$prepareToInterceptTraffic$5(Network.java:258) at org.openqa.selenium.devtools.Connection.lambda$handle$4(Connection.java:330) at java.base/java.util.stream.ForEachOps$ForEachOp$OfRef.accept(ForEachOps.java:183) at java.base/java.util.stream.ReferencePipeline$2$1.accept(ReferencePipeline.java:177) at java.base/java.util.stream.ReferencePipeline$11$1.accept(ReferencePipeline.java:442)

The issue is not reproducible when a non-remote driver is used.

How can we reproduce the issue?
